I18n working in Orca?

["Dorado Martínez, Francisco Javier" <FDMA once es>]

Hi folks 

I am trying to make i18n work in Orca, I have correct the locale
LANGUAGE=es_ES_UTF8, and the orca.mo is generated in compile/installation
step.
But when I run Orca it plays in english instead of spanish. 
> From python I have tried from orca_i18n import _
And then _("Welcome to Orca") for example, and it returns the same string. I
have tried with other strings and  the same occured.

Any help would be appreciated

Thanks

Regards,

Javier
